Description
Technical field
The present invention relates to 3G (Third Generation) Moblie (3
RdG) improve MBMS (MultimediaBroadcast/Multicast Service in, multimedia broadcast/multi broadcast business) method of service conversation re-transmission and MICH (MBMS Indicator Channel, the MBMS announcement/Page Indication Channel) frame structure in this method of realization.
Background technology
According to current 3GPP (3rd Generation Partnership Project, the 3G (Third Generation) Moblie collaborative project) agreement, some kinds of MBMS business classify as a MBMS service groups, and each MBMS service groups all has corresponding sign NI (announcement indication) on the MICH channel.Each user terminal (UE) is all monitored the MICH channel, in case the corresponding N I on MICH channel sign is paged, UE will the starting point the adjustment period of each of MCCH channel (MBMS control channel) removes to read and compare the MBMS service identification number (MBMS Service ID) on the MCCH channel.And under the situation that the MBMS service conversation retransmits, the session identification number (MBMS Session ID) that UE also will get on and read and compare corresponding M BMS business on the MCCH channel at the MCCH channel.
For example: a MBMS service groups has 5 kinds of MBMS business, and every kind of business has the user of 1000 subscription.The data of every kind of MBMS business are made up of 10 to 20 sessions.If 200 users of professional 1 have 1 session to need to retransmit, so according to current 3GPP agreement, the operation that 5000 users of all of this MBMS service groups will be correlated with after the NI sign of receiving on the MICH at this service groups: read and compare the MBMS traffic identification number on the MCCH, read and compare the MBMS session identifier on the MCCH.
That is to say that a MBMS service groups has some kinds of MBMS business, every kind of MBMS business all has thousands of name users.Because all MBMS business of a service groups all have same sign-NI on the MICH channel, so, even if having only a session of a MBMS business retransmitting, no matter whether all users of this service groups (subscribe to this business, also whether received complete MBMS data) all must make response to this paging, starting point adjustment period of each of MCCH channel removes to read and compare the MBMS service identification number on the MCCH channel, and then the session identification number (MBMS Session ID) that also will get on and read and compare corresponding M BMS business on the MCCH channel at the MCCH channel.
Under the normal operation situation of current mobile communications network, the professional packet loss of bag is about 1%, considers that again each MBMS service groups all has some kinds of MBMS business, and every kind of MBMS business all has thousands of name users.So, for most of users (comprising the user who correctly receives the MBMS of partial data) of whole M BMS service groups, the MBMS session retransmits the paging bring and follow-up reads and compare the MBMS Service ID on the MCCH, the operation of MBMS Session ID, in fact all is unnecessary spending.And, for UE, the starting point the adjustment period of each of MCCH channel go to read and compare the information on the MCCH channel, must introduce and interrupt, otherwise will miss this accurate moment.The current process of UE be can interrupt and introduce interruption, and a series of complex operations and expenses such as keeping the scene intact, recover the scene brought.
As seen, according to the mode that the MBMS service conversation in the current 3GPP agreement retransmits, bring a series of unnecessary complex operations and expense (comprising that power consumption and UE handle the consumption of resource) can for most of users.

Fig. 2 is the flow chart that the present invention improves the multimedia broadcast/multi broadcast business conversation repeat method.
Embodiment
At first, the present invention has adopted MICH frame structure as shown in Figure 1, and this MICH frame structure has utilized 1 to 12 spare bits of original MICH frame structure on the MICH channel, has set up session and has retransmitted flag bit.It is the wherein figure place of the arbitrary number in 12 and the permutation and combination of these figure places at the most that session retransmits flag bit.And session to retransmit encoded content on the flag bit (1～12 any all can) can be " complete 0 ", " complete 1 " or other 01 ..., 10 ... or the like form.
Be that example is illustrated all below with 12.
As shown in table 1, flag bit is that the MBMS session is transmitted first or retransmitted especially for " complete zero " expression, and flag bit is a MBMS session ordinary retransmission for " complete one " expression.(certainly, can be that the MBMS session is transmitted or re-transmission especially first for " complete one " expression with flag bit also, flag bit be a MBMS session ordinary retransmission for " complete zero " expression.)

| b 288 | b 289 | …… | b 299 | Implication |
| 0 | 0 | …… | 0 | The MBMS session is transmitted first or is retransmitted especially |
| 1 | 1 | …… | 1 | MBMS session ordinary retransmission |
Like this, the user terminal of this service groups retransmits sign by the monitoring session and just can pick out MBMS session ordinary retransmission or transmission first or special the re-transmission on the MICH channel.
How does UE judge whether oneself has correctly received the data of all sessions of ordered MBMS business?
The MBMS business comprises two kinds of the professional and background service of stream, and the professional real-time live TV stream that broadcasts while the making non real-time professional and that make that is divided into again of stream flows business.
In fact non real-time stream business and background service are exactly to be transmitted in the file of storing on the server of MBMS service provider.In order to be stored on the disk, all files all have regular length, file initial sum end of file sign is all arranged, and be to be divided into several to wrap and transmit, can use the method for inspection of maturations such as CRC (cyclic redundancy code) verification to check whether each bag is wrong during file transfer, and check whether packet loss is arranged.UE has file initial sum end of file sign by checking each file that whether is received, whether length changes, whether there is packet loss to take place, whether received and be surrounded by wrong the generation, just can have been known the data of all sessions that oneself whether correctly received ordered MBMS business.
And for real-time live TV stream business, UE does not know when this business stops.But what at this moment be provided with on the MICH frame structure is to transmit sign first, and its processing method is identical with current relevant 3GPP agreement, and what adverse effect system and user thereof are not had.And live end in a single day, this real-time live TV stream business will be stored in the form of file on the disk of MBMS service provider server.When in case this file retransmits first, " the MBMS session retransmits especially " defined herein exactly, its processing method is identical with current relevant 3GPP agreement, and what adverse effect system and user thereof are not had.
Like this, adopt after the MICH frame structure of the present invention, should be as shown in Figure 2 in the handling process of UE side.
At first, UE goes up in paging/announcement channel (MICH) and monitors all paging informations, and when listening to the paging of affiliated service groups, UE checks " re-transmission flag bit ", and judges it is " transmission first " or " the special re-transmission " or " ordinary retransmission ":
" if ordinary retransmission ", the user for the partial data of the MBMS business that correctly receives its subscription no longer receives the processing of MBMS business datum, continues to go up in paging/announcement channel (MICH) and monitors all paging informations; Otherwise the method for abideing by following " transmission first " or " the special re-transmission " is handled.
If " transmission " first or " the special re-transmission ", UE will the starting point the adjustment period of each of MCCH channel read and compare the MBMS service identification number (MBMS ServiceID) on the MCCH channel, judge whether this business is the MBMS business that the user orders:
If not the MBMS business that this user orders then no longer receives the processing of MBMS business datum, continue to go up all paging informations of monitoring in paging/announcement channel (MICH);
If the MBMS business that this user orders, the session identification number (MBMS Session ID) that UE also will get on and read and compare corresponding M BMS business on the MCCH channel at the MCCH channel, judge further whether the user has correctly received the partial data of this Session, for the partial data that correctly receives this Session, then no longer receive the processing of MBMS session data, continue to go up all paging informations of monitoring in paging/announcement channel (MICH); Otherwise the user just receives the data of this MBMS session, after reception finishes, continues to go up all paging informations of monitoring in paging/announcement channel (MICH).
In sum, the present invention is directed to the session retransmission mechanism of MBMS business, introduced the MBMS session in the MICH frame structure on the MICH channel and retransmitted flag bit.Like this, the user terminal of this service groups retransmits sign by the monitoring session and just can pick out MBMS session re-transmission or transmission first on the MICH channel.
So; when the MBMS session retransmits; the user who has correctly received all session datas of ordered MBMS business just needn't the starting point the adjustment period of each of MCCH channel removes to read and compare the MBMS service identification number (MBMS Service ID) on the MCCH channel; the also session identification number (MBMSSession ID) that needn't get on and read and compare corresponding M BMS business on the MCCH channel at the MCCH channel; UE more needn't introduce interruption; upset the current process of UE, and bring a series of complex operations and expenses such as keeping the scene intact, recover the scene.
Therefore, scheme proposed by the invention can reduce unnecessary complex operations and expense that MBMS session retransmission processes brings for the most of users of MBMS service groups, and the processing resource that can save power consumption and the UE of UE.
Above embodiment is only for the usefulness that the present invention is described, but not limiting the scope of the invention.Relevant those skilled in the art under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, and the technical scheme that all are equal to also should belong within the category of the present invention's protection, is limited by each claim.
